How to get the gene function based on GO id?

Question

[xzpgocxx]

Hello, I have an annotation file that includes two columns: gene_name and GO_id. How to get the gene function in different level based on the GO id?

gene_name                                   GO_id
Unigene60407_cheng_ma_9.6A   GO:0005626,GO:0042995,GO:0005790
Unigene52761_cheng_ma_9.6A   GO:0031981
Unigene21799_cheng_ma_9.6A   GO:0016020
Unigene10085_cheng_ma_9.6A   GO:0044444
Unigene21819_cheng_ma_9.6A   GO:0016020,GO:0005739

Thanks.

You mean GO Description?? ex GO:0042995 ==>cell projection

Yes, Just like :

1. Biological Process

   alcohol metabolic process

   monosaccharide metabolic process

   amine metabolic process

   carbohydrate metabolic process

   metabolic process

   chitin metabolic process

   amino sugar metabolic process

   glucosamine metabolic process

   N-acetylglucosamine metabolic process

2. Cellular Component

   cytoplasm
   carbohydrate binding

   catalytic activity

3. Molecular Function

   chitin binding

   oxidoreductase activity

   pattern binding

   polysaccharide binding

you can download the entire GO file (go.obo)from GO database then parse the data. Simpler way is to get from biodbnet where input will be GO ID and output will be GO Annotation
